The Heavy Duty 22-Stitch Sewing Machine from Elna is constructed with high strength, lightweight, durable cast aluminum alloy metal which provides a strong chassis for the rest of the machine to be assembled into. The outer cosmetic cover and shell of the machine is constructed of strong ABS plastic, and the gears are nylon which results in less noise and friction as well as wear & tear. This device’s heavy duty motor can stitch through a variety of different fabrics, from mending your jeans to creating your own garments and stitching crafts! Its automatic one-step system consistently makes great button holes in exactly the size that you need them; just drop your button into the back of the foot, press the foot pedal and be amazed. Since Elna joined forces with Janome, they have become the world’s largest domestic sewing machine manufacturers and export to more than 100 countries.
